LOAD LIFTING DEVICE FOR RAILWAY CARS Application filed May 28, 1930. Serial No. 456,575.

The device relates to railway freight cars and comprises means forming a part of the roof structure which provides places for attaching load lifting devices, such load lifting devices being used to move heavy articles into and out of the car or move such articles within the car or to place one part of the load over another part, such as double decking automobiles.

The connecting member or beam extends longitudinally of the car and is preferably located adjacent the center of the car or may be positioned near the side plate or one near each side plate, or if desired, may be located in both or in all such positions and still come within the scope of this invention. It may be desirable to raise the load simultaneously from more than one point. The beams may extend the full length of the car and reenforce each and every carline or they may simply include a plurality of carlines and be located as desired. The beams are preferably spaced apart from the roof to provide a space so a chain or rope may be thrown over the beam to support a block and tackle or differential chain or other device.

In the drawing:

Fig. 1 is a vertical transverse section through a railway car roof construction provided with a lifting beam construction embodying my invention,

Fig. 2 is a vertical longitudinal section through the car roof on the line 2-2 in Fig. 3,

Fig. 3 is a fragmentary section on an en larged scale similar to Fig. 1 of the ridge ortion of the roof with the running board structure omitted,

Figs. 4 and 5 are views similar to Figs. 2 and 3, respectively, showing a modified lifting beam construction, ig. 4 being a sectional view on the line 4,4 in Fig. 5,

Figs. 6 and 7 are similar views of another modified lifting beam construction, Fig. 6

' on the line 6-6 in Fig.

7; and

Figs. 8 and 9 are similar views of another modified lifting beam construction, Fig. 8 being a sectional view on the line 88 in Fi 9.

g The drawing shows my improved load lifting device applied to the standard A. R. A. car roof for freight cars, which consists of a channel shape carline 2 comprising substantially vertical walls 3 having lateral flanges 4 at the upper margin of each vertical wall and a plurality of roof sheets 5 secured to said flanges with certain of said sheets overlapping the channel of the carline. This Construction forms a box so that it is impracticable to attach anything to the walls 3 of the carlines on account of the difficulty of getting at the inside head of a rivet (or the nut of a bolt) to remove or replace it. This is a serious condition in building new cars and also in repairing cars. Furthermore, makes it quite difficult to apply a load lifting beam to cars already built.

In my arrangement I attach the load lifting beam 7 to the flanges 4 of the carlines 2 by means of brackets which the carlines by the same rivets 8 which secure the roof sheets 5 to the carlines. To apply my device to existing equipment it is merely necessary to remove and replace a few of the roof sheet rivets 8.

Fig. 1 illustrates the relation of a load lifting beam 7 to the other parts of the car, such as the side plates 10, carline 2, roof sheet 5 and running boards 11.

In Figs. 2 and 3 each load lifting beam 7 is supported by a bracket 13 secured to the carline by the roof sheet rivets 8 and the bracket 13 is provided with a flange 14 upon which the load lifting beam rests. The load lifting beam is spaced apart from the roofing to provide a space to throw a rope or chain over the load lifting beam but the beam is preferably positioned with the lower portion thereof not lower hail the bottom of the carline 16 so as not to restrict the clear vertical space in the car. The bracket 13 is made wide enough, as shown in Fig. 3, to accommodate a plurality of roof sheet rivets to provide the necessary strength. A connector 18 may be positioned below the carline and secured to the beams on the opposite sides of the carline and also to the brackets so as to secure cooperation between adjacent beams.

Figs. 4 and 5 show a modified form wherein the load lifting beam 20 is suspended from are secured to Vides an arrangement the carline by the same rivets 8 which hold the roof sheets 5 to the carline. This beam is deflected to provide a space 21 between the upper part of the beam and the roof sheet 5 so as to permit a rope or chain to be thrown over the beam. The beam is preferably channel shape with flanges 23 at its upper ,margins, which channel is flattened out and offset upwardly, as at 24, at each end of the beam to provide a wide attachment to the carline, as shown in Fig.4.

Figs. 6 and 7 show a modified form where in the beams are suspended from the roof sheet rivets 8 by the brackets .31, each bracket being formed to have an engagement wit-h a wall 3 of the carlineso as to resist the tendency of, the loadlifting beams to shift longitudinally of the car. The'beams are also extended so that their ends (32) respectively engage the walls of the carline to further resist thelongitudinalshifting of the beam. I prefer also to use. the connector 34 to secure: the beams .on oppositesides of the carline together. This construction prowherein a compact, rigid connection of the load lifting beams to the carline is provided. The connector also strengthens the beam to carry a vertical load because itprovides a beam semi-restrained at its ends.

Figs. 8 and 9 show a modified form wheren a stirrup is provided to support the load lifting beam 41 from the roofsheet rivets 8.

:IVhiIeI have shown channel shaped beams, it is understood that any other shape beam may be used. and-still come within thescope Of the invention.

The. accompanying. drawing illustrates the preferred form of the invention, though it is to be understood thatthe invention is not limited to the exact details of. construction shownand described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.

I claim:

1. In a'railway car, the combination of a U-shapedcarline having lateral'flanges at its upper margins, roofing, means securingsaid roofing to said flanges, a bracket secured to said flanges by said means, and a load lifting beam supported by the bracket.

In arailway ear, the combination of a U-shaped carline having lateral flanges at its upper margins, roofing, means securing said flanges, a bracket secured to said flanges by said means, anda load lifting beamsupported by the bracket, said load lifting beam being spaced apart from said roofing.

3. .In a railway car, the combination of a U-shaped earlinehaving lateral flanges at its upper margins, roofing, means securing said roofing to said flanges, a bracket secured to said flanges by said means, and a load lifting beam supported by the bracket, said load lifting beam being spaced apart from said roofing and positioned with its lower parts not lower than the bottom of the carline.
